A series of music-based puzzle games created by Tetsuya Mizuguchi.
In the game, you create squares out of blocks of the same color, which are then erased when the timeline passes over them. As you play, the game will change its "skin", switching its visuals, music, and even the speed the timeline moves.
The series started as a launch title for the
PlayStation Portable in 2004, and is still ongoing to this day. It's had countless releases that span across many systems, including the Xbox 360, PlayStation 3, and PlayStation Vita. The series has also featured various licensed songs from well known artists, such as MONDO GROSSO, The
Chemical Brothers, Fatboy Slim, and many more. It's even had a few collaborations with other games, such as LittleBigPlanet and Rez.
